Did some debugging using the simulator and I finally realized why I
didn't get any tracknum. ID3V2 tags aren't loaded.

The reason? Padding. All my tags (or almost all) ID3V2 tags are at least
2 KB, due to the ripper used... So the ID3V2 tag wasn't read after all.
(The file I tested in standalone mode was ofcourse _not_ padded. :)
